204 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



Huddersfield {G.T.P. and TV. Timsiall)\ and occurs at 

 Everingham (y. Sumner) ; Great Ayton (T.A.L.^ ; Otley 

 {W.M.) ; Bishop's Wood, Selby {S.W.) ; and Sheffield 

 {A.E.H.). 



Nyssia hispidaria W. V. Wheatley Wood, Doncaster ! 

 {H.H.C.) ; Everingham ! ! (/. Stimner). 



Amphydasis prodromapia W.V. Beverley [J.R.L.) ; 

 Everingham! ! "between forty and fifty, including an 

 almost black specimen, in 1898 " (/. Su'mne7'). 



Amphydasis betularia L. The black variety douhleday- 

 aria Mill, has now almost entirely eliminated the 

 ordinary pale form from the South West Riding, and 

 bids fair to do so throughout the county at no distant 

 date. Mr. Corbett records the species *' as mostly dark 

 at Doncaster ; " whilst the form also occurs at Burton 

 Bushes, near Beverley [J.R.L.) ; Everingham {/. Sumner) ; 

 Halifax {A. Gibson-Rohertshaw) ; Loftus-in-Cleveland 

 {T.A.L.)', Pickering [G.T.P.); Sledmere [W.H.) -, 

 Thorne [G.T.P.). 



Cleopa lichenaria W. V. Between Ayton and Stokesley 

 [T.M.) ; Castle Howard (/. Hawkins). 



Boarmia repandata L. I found a beautiful glossy black 

 form in abundance in a wood near Huddersfield in 1887, 

 and the form seems now to be spreading over the 

 county (see E.M.M. of December 1881, p. 161). Mr. 

 A. E. Hall has since found the form commonly near 

 Sheffield ; and it is also recorded from Bradford [J.B.) ; 

 from Rotherham ; and from the east side of the covmty 

 at Saltburn [G.T.P.). Besides this extreme form, other 

 paler varieties occur in which there is a marbling of rich 

 browns and slate colours, and the races seem altogether 

 diff"erent from anything found elsewhere.
